Calderón-Martínez, Nadia R., González-Obando, Ranulfo & García Aldrete, Alfonso N., 2014, Descriptions and records of Cladiopsocidae and Dolabellopsocidae (Insecta: Psocodea: ‘ Psocoptera’) from Valle del Cauca and National Natural Park Gorgona, Colombia, Zootaxa 3889 (1), pp. 1-30 : 22-25

Isthmopsocus foliatus n. sp.

( Figs 80–89 )

Diagnosis. Phallosome ( Fig. 84 ) with three endophallic sclerites, two lateral, similar in shape and a central one, of different shape. Gonapophyses ( Fig. 89 ), wide at base, narrowing distally, acuminate; subgenital plate ( Fig. 87 ) broad, setose, with a small concavity apically.

Description. Male. Color. Head ( Fig. 82 ) brown yellowish, with brown spots on vertex, genae, postclypeus and epistomal sulcus. Compound eyes black, ocelli hyaline. Thorax light brown, with a brown longitudinal band on each thoracic pleuron. Abdomen creamy, with tenuous brown subcuticular rings. Clunium, epiproct and paraprocts light brown. Wings ( Figs 80–81 ) almost hyaline, with a light orange hue, pterostigma opaque, veins pale brown.

Morphology. As in diagnosis, plus the following: posterior border of clunium, over the area of the epiproct ( Fig. 85 ), with a dense field of small papillae. Hypandrium ( Fig. 83 ) anteriorly wide, with sides converging to pointed apex, setae as illustrated. Paraprocts oval, sensory fields with 26 trichobothria on basal rosettes. Epiproct subtriangular, with setae on distal half.

Female. Color. Same as the male.

Morphology. As in diagnosis, plus the following: paraprocts ( Fig. 88 ) oval, setae as illustrated, sensory fields with 20 trichobothria on basal rosettes. Epiproct subtriangular, with field of setae on distal half.

Remarks. This species is similar to I. lanceatus Mockford (1991) , but it doesn’t have the median longitudinal denticles on the hypandrium and the shapes of phallosome, subgenital plate and gonapophyses are different.
